Rhode Island Child Health Study (RICHS)

Mother and infant pairs were enrolled in the Rhode Island Child Health Study (RICHS) at the Woman and Infant's Hospital from 2009 through 2014. This population consists of singleton, term infants (≥37 weeks gestation) born without serious pregnancy complications or congenital or chromosomal abnormalities. Given a priority interest to study fetal growth, the RICHS population was oversampled for both large for gestational age (LGA, >90% 2013 Fenton Growth Curve) and small for gestational age (SGA, <10% 2013 Fenton Growth Curve) infants. ]]> Inclusion: Mothers age 18-40 years, with no life-threatening conditions Infants with no congenital or chromosomal abnormalities Singleton births, gestation to term (≥37 weeks gestation) ]]>
